SEWER- SPECIFICATION forming part of Letters Patent No. 275,802, dated April 17, 1883. Application nieu Augustin, Issa. (No model.)

To all whom it may concern: y

Beit known that we, EDWARD Z. UoLLINcrs, of Camden, in the county of Camden and State of New Jersey, and CHAnLEs F. PIKE, of Philadelphia, in the county ot' Philadelphia and State of Pennsylvania, citizens of the United States, have invented certain new and useful Improvements in Sewer-Inlets, ot' which the following is a specification, reference being 1o had therein to the accompanying drawings,

wherein- Figure l is a vertical section of a sewer-inlet embodying our improvements. Fig. 2 is a horizontal section through the trap of the same. Fig. 3 is a detail section of a modication. Fig. 4 is a section of a moditied form of sewer-inlets provided with our invention; and Fig. 5 is an elevation, partly sectional, ot' same connected to the sewer, the latter being 2o in section.

Our invention has relation to sewers and their inlets, and has for its object to disinfect such devices and prevent the escape of sewergas therefrom.

It is well known that water and other iiuids will absorb a certain amount or volume of sewer-gas, and the more intimately the gas and fluid are commingled together the greater the absorption. It is also Well known that when 3o a body of water or other tuid is divided into small particles or atoms, or when it is sprayed, it presents a larger surface for such absorption and takes up proportionately a greater volume ot" such gas than it does when in a duid condition. Such being the case, it follows that it' a spray of water or other duid be continuously injected into a sewer or its inlet the gas or odors therein will he absorbed by such duid and carried oft thereby. Hence such gases 4o cannot escape from the inlet to pollute the su rrounding` atmosphere. Again, itl such water or duid be commingled with or caused to pass through a disinfectant to `take up the same,

and then injected into the sewer or its inlet in a. sprayed or finely-divided condition, it not only absorbs the gases or odors therein, but

disinfects said parts and keeps them in a clean and wholesome condition.

Our invention accordingly consists ot' the 5o novel combination, construction, and arrangement oi' parts for accomplishing the above-described results, as hereinafter specifically described and claimed.

Referring to the accompanying drawings, A represents a sewer-inlet having a trap, a, of the form shown in Figs. l and 4, or ot' any other suitable construction.

The trap a, in Fig. l consists of an inverted cup, the flange a of which enters the sealinggroove a3, and is provided with a stem or rod, 6o a4, upon which is secured one or more screens or gratings, B B, to prevent coa-rse dirt and garbage or other materials entering trap a to choke up the same.

C represents a pipe connected at c to inlet A, its end c terminating in a nozzle, sprayer, or atomizer, c2, as shown. Said pipe is designed to be connected to the water-main a branch thereof", or a reservoir, so that a continuous running stream of water may pass therethrough to the nozzle c2 and be injectedv into chamber A of inlet A in the form of a spray, or otherwise nely divided or atomized. Each atom or line stream of water as it passes through chamber A presents a surface for contacting with and absorbing any gases or odors that tind their way or are generated therein, and are carried oft' by such Water through trap a to sewer D, as shown in Fig. 5. The pipe C maybe connected to the inlet A, as shown at c, Fig. l; or the exit pipe or conduit A2 thereof may be'fnrnished with such a pipe, as represented at y, Fig. 1, and the sewer D may have one or more ot'said pipes connected thereto at every mile or less of its length, so that a series of continuously-flowing streams of water will be sprayed into such devices to absorb all sewer gas and odors generated therein.

In the line of the pipes C a tank or reservoir, E, is located, in which is placed a. duid or solid disinfectant. Such reservoir is represented at E in Fig. l, the line 2 2 indicating the height ofthe disinfectant therein. As the water passes therethrough it is charged with the disinfectant, and, when sprayed into the l inlet or sewer, disinfects said parts in a very thorough manner.

It' desired, the inlet A may have a disinfectant-containing pocket or chamber formed therein, as shown at E, Fig. 3, the disinfectant be- IOO ing placed upon a screen or grating in said What we claim as our invention ispocket, which serves to divide the water into 1. The combination of inlet A, trap a, and 2 5 iine streams or particles as it passes thercpipe C, terminating in a spraying device, c, through into chamber A 5 or said pocket may and leading to a constant source of water-sup- 5 be constructed and the pipe C, with its nozzle ply, x, substantially as shown and described.

The combination of inlet A, havingrtrap Water or disinfectant-water falling into trap a a, the pipe C, the spraying device c2, and res- 3o provides a runnin g-seal therefor for obtaining ervoir E, substantially as and for the purpose the benecial results of the use of said seal, as set forth.

xo fully described in an application led by us of 3. The inlet A, having groove a3, inverted even date herewith. The pipe C may have a hanged cup or valve a', having stem a, and valve, or its bore may be sized, as desired, for screens or gratin gs B B, substantially as shown 35 regulating the flow of water therethrough, as and described. fully set forth in said application; or a filter, In testimony whereof we affix our signatures 15 G2, may be secured thereto, as shown in Fig. 4. in presence of witnesses.

If desired, a screen, P', or a. plate, P', may

be secured to the inlet A in chamber A', so EDWARD Z. COLLINGS. that water owing through the mouth of the CHARLES F. PIKE. inlet will pass through said screen or fall on 2o said plate and be sprayed or divided into small lVituesses streams to absorb the sewer-gas in the inlet. SA. J.
